Bone and gum grafting

Bone grafting

Bone grafting is the replacement or augmentation of the portion of the jaw bone that anchors the teeth. It's a surgical procedure that's often done to reverse the loss or resorption of bone that may have occurred due to tooth loss, trauma, disease or ill-fitting dentures, and to rebuild the bone structure beneath the gums in preparation for the placement of dental implants or other tooth replacements. When bone graft is implanted in the jaw, it doesn't just simply fill a void in the bone; it may also help promote new bone growth in that location. When successful, bone grafting can restore both the height and width of your jaw bone.

There are several bone graft options:

Autogenous Bone Grafts. Also called autografts, these types of grafts are made from the patient's own bone, taken from elsewhere in the body. Typical sites include the chin, jaw, bone of the lower leg (tibia), hip (iliac crest) or the skull (cranium). Allogeneic Bone. Allogeneic bone, also called allograft, is bone derived from a genetically unrelated member of the same species. This method of bone grafting is not practiced in Hungary.

Alloplastic Bone Graft. Alloplastic bone graft materials are most common in use; they consist of either natural or synthetic base substances. Natural in substance, the hydroxyl apatite bio-ceramic is usually extracted from calf bone. The synthetically generated absorbable tricalcium phosphate is the most widely spread material in use.  In cases of minimal bone grafting, the GBR technique, or guided bone regeneration technique is applied. GBR is a procedure in which a membrane is placed over the bone graft site. This membrane further encourages new bone to grow and also prevents the growth of scar tissue in the grafted site. This technique can be applied parallel with implantation procedures.
